Specification of Letters Patent.

Patented Aug. 25, 1914.

Application filed July 10, 1913. Serial No. 778,369.

To all whom it may concern Be it known that I, RALPH L. QUEEN, a citizen of the United States, residing at Millville, in the county of Cumberland and State of New Jersey, have invented certain new and useful Improvements in Trolley- Guards, of which the following is a specification.

This invention relates to trolley guards and more particularly to a mechanism which is associated with the trolley pole for holding the trolley wheel in a juxtaposition with the wire, the mechanism being so arranged as to prevent the casual displacement of the wire and at the same time allowing for the disconnecting of these two members when it is so desired by the operator.

An object of the invention resides in the provision of jaws which are hingedly mounted on the harp in such a manner as to allow for the simultaneous opening of the jaws together with the downward movement of the trolley pole, when pressure is exerted on the trolley pole rope.

Other objects as well as the nature, characteristic features and scope of my invention will be more readily understood from the following description taken in connection with the accom Janying drawings and pointed out in the claims forming a part of this specification.

In the drawings :Figure 1 is a side clevation of the device constructed in accordance with my invention, showin the same as arranged on a trolley pole; ig. 2 is a sectional view taken on the line 2-42 of l ig. 1: Fig. 3 is a top plan fragmentary view of the same; Fig. t is an elevation of one of the jaws, looking at the inner side thereof, and showing the manner of connection between the same and the harp, only a portion of the harp being shown; and l ig. 5 is a longitudinal sectional view of one of the jaws showing to advantage the spring pressed block therein.

In the drawings wherein is shown the preferred form of my invention the numeral (i represents a trolley pole on which is arranged the sleeve 7 being of any suitable construction, conforming to the configuralion of the trolley pole. The upper end of the sleeve 7 is connected to the harp 8 in which is journalcd the ordinary trolley wheel 9. llingcdly mounted on the upper end of the harp 8 are jaws 10 which are connected to the harp through the medium of elongated bolts 11, the opposite end of the jaws 10 comprising segmental blocks 12 which are recessed midway the ends thereof adapted for the reception of the blocks 13, a spring 14 being positioned between the sides 10 of the jaws and the blocks 13 so as to provide yielding blocks. A coil spring 11 is encircled around the shank of the bolt 11 and has its opposite ends in engagement with said jaws and said guard for normally holding the former in a closed position as shown to advantage in Fig. 2. The outer faces of the blocks 13 have portions thereof cut-away as indicated at 15, the cutaway portion on the one block alternating with the cut-away portion of the opposite block whereby to provide an interlocking engagement between these two elements for preventing the accidental displacement of the trolley wire.

A cylinder 16 is positioned directly below the harp 8 and has mounted therein a plunger 17 which is engaged to the one end of the spring lb. The outer end of the plunger 17 has mounted thereon a hook 19 by which the plunger is operated in the cylinder, the spring being secured to the plunger so as to automatically bring the same back to its normal position after the pressure is released from the hook. Extending outwardly at right-angles to the jaws 10 are looped-eyes 20, each of which is connected to the one end of the link 21, the opposite end of the link engaging the looped-eye 22 of the wire frame .23. One of the links 21, is arranged on each side of the jaws 10 as above stated, and is provided with loopedeyes in the opposite ends thereof, the loopedeye in the one end engaging with the loopedeye 20 of the jaw, and the looped-eye of the opposite and engaging with the looped-eye 22 of the wire frame 23. The wire frame 23 has a midway portion thereof bent so as to form a looped-eye 24 which engages over the hook 19 thereby allowing for the simultancous opening of the jaws l0 and the downward movement of the trolley pole (3 when pressure is exerted on the rope On close aiplication to the drawings it will be seen that the improved guard comprises two parts which are connected through the medium of bolts 26 or the like, and is made of wood, metal or any other suitable material. Although the guard is shown to comprise two parts it is to be understood that the same may be made in a llll) lll) single piece if so desired without departing from the spirit of the invention.

Tn operation the sleeve 7 is slidably mounted on the trolley pole G, and the trolley wheel 9 journalcd within the jaws 10, the jaws 10 being of such a length as to allow the upper end tliereof to extend beyond the trolley wheel and the trolley wire, and completely housing the same so as to eliminate all danger of the wire being accidentally displaced from the wheel when the vehicle is rounding curves, or the like where undue lateral thrust is exerted on the trolley wire.

The provision of the spring pressed blocks 11) in the jaws, allows for the wire to be placed therein on the wheel, without the necessity of opening the jaws of the wire frame 23, although if desired the same may be coi'iveniently done by the operator of the device. By providing the plunger 17 on the interior of the cylinder 16 it is obvious that when it is desired to release the wire from the trolley wheel, that both the jaws 10 may be opened and the trolley ole 6 brought downwardly on the top of tie car or the vehicle to which it is attached,as the spring pressed plunger 17 allows for the movement of the wire frame 23 for performing both of the above operations.

lt will be understood that the above description and accompanyin drawings compreiend only the general and preferred form of my invention and: that various minor changes in details of construction, proportion and arrangement of the parts may be made within the scope of the appended claims and without sacrificing any of the advantages of my invention.

llaving thus fully described my invention, what I claim as new and desire to secure by Letters Patent is 1. A trolley guard including a harp, a wheel journaled in said harp, an elongated sleeve extending from said harp for engagement with a trolley pole a cylinder depending from the bottom at the harp adjacent said sleeve, jaws hingcdly mounted on the upper edges of said harp, a spring rossed block carried by each of said jaws raving yielding engagement with each other, a plunger arranged in said cylinder, and a frame. the o posite ends of which are engaged with t ie sides of said jaws, said frame iaving connection midway the ends thereof with the. end of said plunger for the purpose specified.
